for the more effective parenting subgroup. Father mental health was significantly associated with BD and with CP for the more effective, but not for the less effective, parenting subgroups. However, these differences were not reflected in mediation z-scores because group differences were not apparent in both upstream and downstream paths for individual mediators. Thus, although the main effect of family density of alcoholism on BD and CP was somewhat stronger for the less effective parenting subgroup, mediated associations between density and child behavior through current parent characteristics appeared to be similar between the subgroups.
